TO ALL WHOM ITMAY-CONCERN:

`Be it known that I, SAMUEL F. SHADBOLT, of the town of Huntington, in the county of Sulfolk, and State of. New York, have invented a new and improved Valve-Stopple; and I do hereby declare that the following is a. full and exact d escription thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon. y

Figure 1 is a plan view of the valve-stopple separate from the bottle D., as seen in gs. 2, 3, and 4.

Figure 2 is an end view of the bottle'D in gs. 3 and 4.

Figure 3 is a side elevation, D the bottle, E the collar, b b the Wire, B the arm or shaft.

Figure 4 is a out section 'of iig. 3.

The nature of my invention consists in providing the upper part of a neckless bottle, or its equivalent,-

with a rubber valve or stopple attached to a shaft, and secured to the top of the Abottle in a groove which allows the shaft to which the valve or stopple is attached to oscillate freely, thus opening and shutting the bottle as force is applied to the inner lower surface of the rubber valve by the gaseous contents of the bottle within or by turning the handle of the shaft to which the rubber valve is attached from without.

To'enable others skilled in the art-to make and use my invention, I will proceed to describe its construction and operation. l

The bottle to lwhich my valvc-stopple maybe applied is made of glass, or-of any other material Aof which bottles arel or may be made', and in the same manner, and in any desirable shape, but without necks. The diameter ofthe mouth of the bottle ismade about three-fourths of that of the diameter of the top of the bottle, which is made slightly convex.. Around the mouth of the bottle I cut the small groove F, in which I place a wire, or its equivalent, which, passing over the ends of the shaft B, to which the rubber valve is attached, holds it firmly in its place, while allowing the shaft to oscillate freely when force is applied to it. Across the mouth of the bottle, at either side of the centre, I cut a groove, in which the shaft to which the rubber valve is attached is placed, as seen at G, figs. 2 and 4. I make my valve or stopple of a piece of rubber, or its equivalent. I make it a little larger than the mouth of the bottle, and of the same shape, sothat when forced vup against the p under side of the mouth, it completely and hermetically closes the orifice. This rubber valve A is attached in the centre. to the projection C of the shaft B by the rivet a, as seen at figs. 1 and 2; the shaft B, with the rubber valve attached, be'ng placed in the groove G and secured by the wire b passing around' in the groovcF. The gaseous liquid is introduced by opening the rubber valve by the handle, which, when left go, closestightly on the under side of thelmouth of the bottle, partly by the elasticity of the rubber valve, which in opening is pressed against the side of the bottle, and partly from the force of the gaseous contents of the bottle. Should the elasticity of the rubber valve be insucient to close the .orifice tightly, when the contents of the bottle are not of a gaseous nature, a ,rubber band, fastened to the handle and to a knob on the side of the bottle, may be used, as seen at H, tig. 3, or by a.

Theadvantages of'myvalve-stopple are, first, it being easily detached from the bottle, and the mouth being wide,`without a neck, the bottle is more easily cleaned than other bottles; second, it being self-acting, saves the cost of corks and the labor of corking and wiring, also prevents insectstand dirt from getting into the bottles when empty; third, the contents of the bottle. are more easily and quickly emptied than any now in general use; fourth,.the valve beingsecurely fastened, there is no possibility ofthe gas forcing it out, while'the bottle is less liable to break in theprocess of corkiug,'as is frequently the case in corking bottles containing gaseous liquids; fifth, it is more easily opened in pouring out the liquid, and can be held in any position.

What@ claim, and desire to secure by Letters Patent, is--- A valve-stopple for bottles, composed of rubber, or its equivalent, attached to a shaft, substantially as described and for the purpose set forth.
